The Koss KEB90 earphones deliver clear highs and punchy bass when paired with a DAC, but many users find the stock sound too bright and lacking bass without one. Build quality is a mixed bag—some appreciate the detachable cables and included tips, while others note flimsy wires and uncomfortable foam tips. Overall, they are a good value for the sale price, especially for those willing to use DSP correction or aftermarket ear tips.
Pros
- Clear highs with DAC
- Punchy bass with DAC
- Detachable cable design
- Comfortable silicone tips
- Good value on sale
Cons
- Bright sound without DAC
- Lack of bass without DAC
- Flimsy cable quality
- Uncomfortable foam tips
- Crinkling sound when inserting
